The present invention relates to pin plugs.
Pin plugs have been proposed with inner contact member in the form of a pin made of electrically conductive metal, an outer contact member in the form of a hollow cylindrical body made of electrically conductive material, and an electrically insulating member for fixing the inner and outer contact members in position in an electrically isolated manner, whereby one of two conductors of an electric cable can be connected to said inner contact member and the other conductor to the outer contact member.
Such pin plugs are used in various electronic and electric apparatuses For example, in an audio apparatus of a system component type, various components such as a radio tuner, a pre-amplifier, a main amplifier, a record disc player, a magnetic tape deck, a loudspeaker system are interconnected by means of electric cables having pin plugs at their ends.
In one previously proposed pin plug, use is made of an electrically insulating plate and the inner and outer contact members are fixed in position by means of the insulating plate Then the assembly is covered with an electrically insulating cover by moulding Such a pin plug cannot be manufactured in a simple manner and has poor electrical properties, particularly a poor insulating characteristic In another previously proposed pin plug, the inner and outer contact members are inserted at suitable positions in moulds and are fixed in position by moulding a body of electrically insulating material This pin plug has relatively good electrical properties, but its mechanical strength is poor Such a pin 50 plug cannot be disassembled after the outer moulded body has been formed, whereby if the plug becomes defective or damaged no internal repairs are possible, the plug and cable attached thereto may become useless 55 According to the invention, there is provided a demountable pin plug comprising an inner contact member in the form of pin made of conductive material, an inner insulating member comprising two generally 60 semi-cylindrical halves made of insulating material said halves, when removed from the plug, being movable apart from a position in which they are held together, by means on the two halves, said inner insu 65 lating member having an internal cylindrical space extending in an axial direction and receiving said pin, the pin and the inner insulating member having means for fixing releasably the pin in position in said 70 cylindrical space, an outer contact member comprising two semi-cylindrical halves and surrounding an outer surface of said inner insulating member, the inner insulating member and the outer contact member 75 having means for locating the outer contact member in position on the outer surface of the inner insulating member in a removable manner, and an outer insulating member comprising a hollow cylindrical 80 body made of an insulating material and enclosing in a realeasable manner an assembly formed by the pin, the inner insulating member surrounding the pin and the outer contact member surrounding the inner in 85 sulating member so as to hold the assembly in position, the pin being connectable to one of two conductors of an electric cable, the other conductor of which is connectable to said outer contact member, with 90 ( 21) W) ( 11) 1 568 867 1 568 867 said cable slidably passing through said outer insulating member.
Embodiments of the invention will now be described, by way of example only, with reference to the diagrammatic drawings, in which:
Figure 1 is a perspective view of a pin plug according to the invention; Figure 2 (a) and 2 (b) are perspective views showing inner and outer surface configurations, respectively of an inner insulating member; Figure 3 is a perspective view illustrating inner and outer contact members and an outer insulating member; Figure 4 is a perspective view showing a manner of fixing a pin contact member in the inner insulating member; Figure 5 is a perspective view depicting an assembly of the pin and inner insulating member; Figure 6 is a perspective view showing how an outer contact member is located on the assembly of Figure 5; Figure 7 is a perspective view illustrating an inner surface configuration of a modified form of inner insulating member; Figures 8 a and 8 b are perspective views respectively showing two halves of another modified form of inner insulating member; Figure 9 is a perspective view depicting two outer contact member halves which cooperate with the inner insulating member shown in Figure 8; and Figure 10 is a perspective view showing the assembly of the pin, inner insulating member and the outer contact member and an outer insulating member.
Figure 1 is a perspective view illustrating a preferred embodiment of a pin plug according to the invention The illustrated pin plug, which is commonly termed a "co-axial connector", comprises an inner contact member 1 in the form of a pin made of electrically conductive sheet metal and an inner insulating member 2 in the form of a hollow generally cylindrical body made of an electrically insulating material such as a hard resin As will be explained later the inner insulating member 2 consists of two semi-cylindrical halves The pin plug further comprises an outer contact member 3 in the form of a hollow cylindrical sheath made of electrically conductive sheet metal and an outer insulating member or body 4 made of a relatively resilient insulating material The outer contact member 3 also consists of two semicylindrical halves The outer insulating member 4 comprises a cup-shaped portion with an elongate hollow extension 5 through which an electric cable 6 having two conductors 7 and 8 passes The internal diameter of the extension 5 is such that the outer insulating cover 4 can slide along the cable in a relative smooth manner.
Figures 2 a and 2 b show the detailed construction of the inner insulating member 2.
As described above, the inner insulating member 2 consists of the two semi-cylin 70 drical halves 2 a and 2 b which are integrally formed by moulding These two halves are connected to each other along one edge 2 c which is made thin to constitute a hinge.
Thus the two halves 2 a and 2 b can be free 75 ly pivoted about the edge 2 c On the inner surface of the half 2 a is integrally formed a resilient projection 2 d having a tapered tip 2 e the projection 2 d lying adjacent the edge opposite to the edge 2 c In a corres 80 ponding position in the inner surface of the other half 2 b there is formed a rectangular hole 2 f which receives the projection 2 d.
When the two halves 2 a and 2 b are pivoted together, a stepped portion 2 g of the pro 85 jection 2 d engages with a ridge of the hole 2 f so that the two halves 2 a and 2 b are firmly coupled to each other The tapered tip 2 e facilitates insertion of the projection 2 d into the hole 2 f Since the projection 2 d 90 is resilient, when its tapered tip 2 e is pushed by means of a suitable tool such as a needle the two halves may be easily disengaged In the inner surfaces of these halves 2 a and 2 b there are formed semi 95 circular recesses 2 h and 2 i respectively extending in an axial direction Thus in the coupled condition there is formed a hollow cylindrical space in which the inner contact pin 1 can be installed On the inner 100 surface of the semi-circular recess 2 i is integrally formed a small projection 2 j in the form of a pin This projection 2 j serves to fix the inner contact pin 1 in position in an assembled condition Further on the 105 outer surface of the respective halves 2 a and 2 b are formed two depressions 2 k, 21 and 2 m, 2 n, respectively The function of these depressions will be explained later.
Figure 3 is a perspective view illustrating 110 the configuration of the inner and outer contact members 1 and 3 The inner contact pin 1 has a rounded tip la and a clamping terminal lb by means of which the conductor 7 is connected to the pin 1 Near 115 the clamping terminal lb is formed a hole lc into which is inserted the projection 2 l formed in the inner insulating member half 2 b when the pin 1 is installed in the semi-circular recess 2 i of the half 2 b so that 120 the pin 1 is fixed in position in the hollow cylindrical space formed by the assembled halves 2 a and 2 b.
The outer contact member 3 consists of two semi-cylindrical halves 3 a and 3 b These 125 two halves 3 a and 3 b are placed on the outer surface of the outer insulating member 2 In these outer contact member halves 3 a and 3 b are integrally formed inwardly bent lugs 3 c, 3 d and 3 e, 3 f, respectively 130 1 568 867 When the outer contact member halves 3 a and 3 b are placed around the inner insulating member 2, the lugs 3 c and 31 engage with the depressions 2 k and 21, respectively and the lugs 3 d and 3 e engage with the depressions 2 N and 2 m, respectively.
Thus the outer contact member halves 3 a and 3 b are located in place in a stable manner The outer contact member half 3 a has integrally formed a clamping terminal 3 g by means of which the conductor 8 is connected to the outer contact member half 3 a In the assembled condition the two outer contact member halves 3 a and 3 b are electrically connected to each other, because side edges of these halves 3 a and 3 b are in contact In order to avoid relative displacement of these halves 3 a and 3 b in the axial direction, on the side edges of these halves are formed semi-circularcut away portions 3 h, 3 i and corresponding semi-circular projections 3 j, 3 k, respectively Moreover the rear ends of these two halves 3 a and 3 b are slightly bent inwardly and are inserted in circular recesses 2 o and 2 p In this manner the outer contact member halves 3 a and 3 b can be firmly located in position around the outer surface of the inner insulating member 2.
In the outer contact member half 3 b there is further formed a resilient strip 31 having a raised tip portion 3 m As will be explained later, when the assembly of the pin 1, the inner insulating member 2 and the outer contact member 3 is inserted into the interior space of the outer insulating cover 4, the raised tip portion 3 m of the outer contact member half 3 b will snap into a rectangular recess 4 a formed in the outer insulating cover 4.
Figure 4 is a perspective view illustrating how the inner contact pin 1 is located in the semi-cylindrical recess 2 i of the inner insulating member half 2 b The smal projection 2 j formed on the inner surface of the recess 2 i is inserted in the hole lc formed in the pin 1, so that the movement of the pin 1 relative to the inner insulating member 2 in the axial direction as well as a rotational movement of the pin 1 can be effectively prevented.
After the pin 1 has been placed in the recess 2 i of the inner insulating member half 2 b as shown in Figure 4 the two halves 2 a and 2 b are coupled together by pivoting the half 2 a along the edge 2 c and are locked together by means of the projection 2 d and the hole 2 f so as to obtain an assembly composed of the pin 1 and inner insulating member 2 as shown in Figure 5 In Figure there is illustrated a cut away portion 2 q at the edge 2 c of the inner insulating member 2 This cut away portion 2 q serves to receive the raised portion 3 m of the resilient strip 31 when the latter is depressed.
Therefore when the outer contact member 3 is placed around the inner insulating member 2, the outer contact member half 3 b is placed in such a manner that the resilient strip 31 faces the cut away portion 70 2 q As shown in Figures 2 and 4 the inner insulating member halves 2 a and 2 b have formed at their edges opposite to the edge 2 c, inwardly cut away portions 2 r and 2 s, respectively When these two halves 2 a and 75 2 b are assembled together these cut away portions form a space for accommodating the clamping terminal 3 g and the conductor 8 connected thereto.
Figure 6 is a perspective view illustrat 80 ing the assembly of the pin 1, the inner insulating member 2 enclosing the pin 1 and the outer contact member 3 surrounding the inner contact member 3 This assembly is inserted in the space of the outer 85 insulating member 4 in such a manner that the raised tip portion 3 m of the resilient strip 31 of the outer contact member half 3 b fits into the recess 4 a formed in the outer insulating cover 4 In this man 90 ner the complete pin plug shown in Figure 1 can be obtained As can be seen in Figure 1 the direction of the contact surfaces of the two inner insulating member halves 2 a and 2 b is perpendicular to the direction 95 of the contact surfaces of the two outer contact member halves 3 a and 3 b viewed in the axial direction and thus the mechanical strength of the pin plug is very large.
The pin plug particularly described can 100 be easily manufactured and has excellent insulating properties being particularly good Moreover, the plug can be easily disassembled and thus even if the plug becomes damaged or the conductors be 105 come disconnected, it can be repaired in a very simple manner.
Figure 7 is a perspective view showing a modified form of the inner insulating member 2 In this embodiment the parts which 110 are the same as those of the previous embodiment are denoted by the same reference numerals In this embodiment on the semi-circular inner surface 2 h of the inner insulating member half 115 2 a is formed a recess 2 t extending in a lateral direction at right angles to the axial direction and on the inner surface of the semi-circular recess 2 i of the other inner insulating member half 2 b is integrally 120 formed a semi-cylindrical projection 2 u.
When the two halves 2 a and 2 b are assembled after the pin 1 has been inserted in the recess 2 i of the half 2 a, the projection 2 u is inserted into the recess 2 t Therefore the 125 conductor 7 connected to the pin 1 is clamped between the projection 2 u and the recess 2 t so that the conductor 7 cannot be pulled out in the axial direction.
Figures 8 a and 8 b show yet another modi 130 1 568 867 fled form of the inner insulating member of the pin plug In this embodiment two inner insulating member halves 2 a and 2 b are formed as separate bodies and these two halves are releasably connected together by means of interengaging pins 2 v and holes 2 W formed in the contact surfaces of these halves 2 a and 2 b Moreover, in this embodiment in the outer surface of the respective half there are formed four rectangular depressions 2 k, 2 k', 21, 21 ' and 2 m, 2 m', 2 N 2 n', respectively (in Figure 8 b only the two depressions 2 k and 2 k' can be seen).
Figure 9 is a perspective view showing two outer contact member halves 3 a and 3 b which cooperate with the inner insulating member shown in Figures 8 a and 8 b.
In these outer contact member halves 3 a and 3 b are formed inwardly bent projections 3 c, 3 c', 3 d, 3 d' and 3 e, 3 e', 3 f, 3 f', respectively When the outer contact member halves 3 a and 3 b are placed around the inner insulating member, the projections 3 c, 3 c' and 3 d, 3 d' of the half 3 a fit into the recesses 2 m, 2 m' and 21, 21 ' of the inner insulating member halves 2 a and 2 b, respectively and the projection 3 e, 3 e' and 3 f, 3 f' of the other half 3 b fit into the recesses 2 k, 2 k' and 2 n, 2 n' of the inner insulating member halves 2 a and 2 b respectively.
Figure 10 is a perspective view showing the assembly of the pin 1, the inner insulating member halves 2 a and 2 b and the outer contact member halves 3 a anad 3 b As shown in Figure 10 the contact surface of the halves 2 a and 2 b is perpendicular to the contact surface of the halves 3 a and 3 b in the coupled condition Thus the relative movement of these halves in the axial and circumferential directions can be effectively avoided The assembly is releasably inserted in the interior of the outer insulating member 4.
The present invention is not limited to the embodiments described above, but many modifications are possible within the scope of the appended claims For example the means for fixing the pin 1 in the inner insulating member 2 may be formed in various ways For instance an outwardly projecting lug may be formed in the pin 1 and a corresponding recess may be formed in the inner surface 21 of the insulating member half 2 b Further the number of projections 2 e and the recesses 2 f is not limited to one: for example a pair of such projections and recesses may be formed.
Moreover a resilient projection similar to the resilient projection 31 formed on the outer contact member half 3 b may be formed in the outer contact member half 3 a The electric cable may be a shielded cable, in which case an inner conductor will be connected to the outer contact member 3.
